Comprehensive insights on treatment modalities with conventional and herbal drugs for the treatment of duodenal ulcers.

Areas of the body accessible to gastric secretions, such as the stomach and duodenum, are most commonly damaged by circumscribed lesions of the upper gastrointestinal tract mucosa. Peptic ulcer disease is the term for this illness (PUD). About 80% of peptic ulcers are duodenal ulcers, with stomach ulcers accounting for the remaining 20%. Duodenal ulcers are linked to the two primary results about Helicobacter pylori infection and COX inhibitor users. Additional causes might include drinking, smoking, stress, and coffee consumption. The indications and symptoms of a duodenal ulcer depend on the patient's age and the lesion's location. For duodenal ulcers, proton pump inhibitors (PPIs) are the usual course of treatment. This comprehensive study included an in-depth literature search in the literature and methods section using electronic databases such as PubMed, ScienceDirect, and Google Scholar. The search method included publications published from the inception of the relevant database to the present. Inclusion criteria included studies investigating different treatment options for duodenal ulcer disease, including traditional pharmacotherapy and naturopathic treatments. Data mining includes information on treatment techniques, treatment outcomes, and possible synergies between conventional and herbal treatments. In addition, this review critically examines the available information on the effectiveness, safety, and possible side effects of different treatments. The inclusion of conventional and herbal treatments is intended to provide a comprehensive overview of the many treatment options available for duodenal ulcer disease. A more comprehensive and personalized treatment plan can be achieved by incorporating dietary changes, lifestyle modifications, and, if necessary, herbal therapies to complement other treatments normally.

Beyond the adverse effects of the systemic route: Exploiting nanocarriers for the topical treatment of skin cancers.

Skin cancer is a heterogeneous disease that can be divided into two main groups, melanoma and nonmelanoma skin cancers. Conventional therapies for skin cancer have numerous systemic side effects and a high recurrence rate. Topical treatment is an alternative approach, but drug permeability remains a challenge. Therefore, nanocarriers appear as important nanotechnology tools that reduces both the side effects and improves clinical outcomes. This is why they are attracting growing interest. In this review, scientific articles on the use of nanocarriers for the topical treatment of skin cancer were collected. Despite the promising results of the presented nanocarriers and considering that some of them are already on the market, there is an urgent need for investment in the development of manufacturing methods, as well as of suitable toxicological and regulatory evaluations, since the conventional methods currently used to develop these nanocarriers-based products are more time-consuming and expensive than conventional products.

miRNA-encapsulated abiotic materials and biovectors for cutaneous and oral wound healing: Biogenesis, mechanisms, and delivery nanocarriers.

MicroRNAs (miRNAs) as therapeutic agents have attracted increasing interest in the past decade owing to their significant effectiveness in treating a wide array of ailments. These polymerases II-derived noncoding RNAs act through post-transcriptional controlling of different proteins and their allied pathways. Like other areas of medicine, researchers have utilized miRNAs for managing acute and chronic wounds. The increase in the number of patients suffering from either under-healing or over-healing wound demonstrates the limited efficacy of the current wound healing strategies and dictates the demands for simpler approaches with greater efficacy. Various miRNA can be designed to induce pathway beneficial for wound healing. However, the proper design of miRNA and its delivery system for wound healing applications are still challenging due to their limited stability and intracellular delivery. Therefore, new miRNAs are required to be identified and their delivery strategy needs to be optimized. In this review, we discuss the diverse roles of miRNAs in various stages of wound healing and provide an insight on the most recent findings in the nanotechnology and biomaterials field, which might offer opportunities for the development of new strategies for this chronic condition. We also highlight the advances in biomaterials and delivery systems, emphasizing their challenges and resolutions for miRNA-based wound healing. We further review various biovectors (e.g., adenovirus and lentivirus) and abiotic materials such as organic and inorganic nanomaterials, along with dendrimers and scaffolds, as the delivery systems for miRNA-based wound healing. Finally, challenges and opportunities for translation of miRNA-based strategies into clinical applications are discussed.

Nanocarrier-based dermopharmaceutical formulations for the topical management of atopic dermatitis.

Atopic dermatitis (AD) is a chronic disease that affects the skin, and that is characterized by highly itchy inflammation, frequent eczematous lesions, and a fluctuating course. The current treatment consists of a multi-stage approach that aims to establish persistent disease control towards the improvement of the quality of life of the patients. Topical therapy is the basis of AD treatment, however, due to the difficulty of crossing the skin barrier, topical application of drugs remains a challenge. In fact, in addition to the low skin bioavailability, and limited accessibility to deeper skin of the drugs - due to difficulty in penetrating the epidermis - implemented drugs in the clinical are associated with serious adverse effects, which are responsible for safety and efficacy limitations, leading to a reduction in patients' compliance. Nanotechnology arises as an emerging approach for the treatment of AD, allowing for controlled release, targeted delivery, improved penetration, and bioavailability of drugs assets, resulting in marked improved therapeutic efficacy and reduction of adverse effects. Although its promising outputs, additional studies are needed to recognize the toxicological characteristics, cost-benefit, and long-term safety of nanocarriers applied to this end. Advanced drug delivery systems, particularly nanoemulsions, liposomes, ethosomes, transfersomes, solid lipid nanoparticles, nanostructured lipid carriers, nanocrystals, polymeric nanoparticles, and polymeric micelles have been used, and are thoroughly addressed in this review as promising nanoformulations towards the topical treatment of AD.

Nano- and microparticle-stabilized Pickering emulsions designed for topical therapeutics and cosmetic applications.

Pickering emulsions are systems composed of two immiscible fluids, which are stabilized by solid organic or inorganic particles. These solid particles include a broad range of particles that can be used to stabilize Pickering emulsions. An improved resistance against coalescence and lower toxicity, against conventional emulsions stabilized by surfactants, make Pickering emulsions suitable candidates for numerous applications, such as catalysis, food, oil recovery, cosmetics, and pharmaceutical industries. In this article, we give an overview of Pickering emulsions focusing on topical applications. First, we reference the parameters that influence the stabilization of Pickering emulsions. Second, we discuss some of the already investigated topical applications of nano- and microparticles used to stabilize Pickering emulsions. Afterwards, we consider some of the most promising stabilizers of Pickering emulsions for topical applications. Ultimately, we carried out a brief analysis of toxicity and advances in future perspectives, highlighting the promising use of these emulsions in cosmetics and dermopharmaceutical formulations.
